It does not "go off" all at once, but it does so a heckuva lot faster than smokeless. Want to see for yourself? Take an 8 ft. long 1 x 6 and pour as thin a line of smokeless on it as you can for the entire length ........... maybe 3/8" to 1/2" wide and 7 ft. long. Do this outside where there are no other combustibles. Now, light the end of the string of smokeless and see how long it takes it to burn. Then, turn the board over and pour an equivalent size line of black powder down the board's length. Now, light the end of it and stand back. The black will burn to the other end so fast you can't follow it with your eyes.
We used to do this as part of a m/l rifle demonstration for hunting clubs and other interested groups. No, it doesn't burn all at once, but it is lightning quick. Detcord doesn't burn all at once either, but it does burn at about 6400 meters/second. Let that sink in a bit.
